Coagula MIDI Ribbon Controller 2.0

Coagula MIDI Ribbon Controller 2.0

A few months ago I published a post on how to make a MIDI Ribbon Controller with Arduino. In the meantime I had a few ideas to improve both hardware and software and also felt the need to change many parameters without having to reprogram every time Arduino. Finally I placed the controller in a case, thanks to Laura who built it. So this is version 2.0 of my MIDI Ribbon Controller, which finally becomes a much more practical tool.

How to build a MIDI ribbon controller with Arduino

There are many professional MIDI controller out there: keyboards, drum pads,    mixer, pedals, etc.  One type of controller that interests me most is the ribbon controller because I wanna try to emulate with the  software  plugins what can be done with instruments such as the Ondes Martenot. I think that this type of controller  fits very well to control virtual instruments such as strings and horns, as it is characterized by a position and pressure sensitive   ribbon, so you can control in a very intuitive way the notes pitch and velocity  .   I  decided to do a MIDI ribbon controller using Arduino.

Gakken SX-150 hacking the controller - tutorial

 In another post I wrote about the Gakken SX-150, now I explain how I created a "giant" controller (50cm) for this mini synthesizer, but in order to make this change I had to first understand a little more about the original control system.
The strip on the Gakken SX-150 is simply a resistor of about 75 Kilohom. Looking at the schematics I found on the Matrixsynth blog I could think for an alternative to the control system of Gakken.
I used a sensor called Spectrasymbol Softpot parallel to the standard sensor.
This sensor is available in various lengths, I bought the 50cm long (the maximum available).
